Letters Patent No. 70,209, dated October 29, I867.

IMPROVEMENT -IN THE GONS'I'RUGTION 0E' GRUET-CASTERS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WESTL E. IIAWKINS, of the city, county, and State of ew York, have invented a new and useful Improvement in Cruet-Casters; and I do herebylcelare that the following is a. full, clear, and exact description thereof, which will enable others skilled in the art to ineke and use the same, reference being had to the accompanying drawings, forming part of this specification.V v

This improvement has reference tothe manner in which the apertures, through which the cruets of a tableeaster pass, are formed and completed; and the invention consists in forming the bead on the centre-plate of the caster by a. peculiar and greatly improved method, and of one and the sa'me piece of metal, as will be hereinafter described. Y

Figure I represents a centre-plate of a table-caster, showingr the holes or apertures in which the cruets are placed. l

Figure 2 is a cross-section of the same through the line z x. Figure 3 represents a plate, which is designed to illustrate the manner of forming the apertures; and

Figure 4 is a section of the lsame through the line'y y. i

Similar letters of reference indicate like parts.

A represents the centre-plate of the castergB reprcscntsthe aperturespforfcruets.' C is the centre hole, through which the'pivot passes, on which the centre-piece revolves. For the purpose of rendering the plate A suileiently strong and stift` Where the eruets are set in, it has always been customary to pu-neh`the holes and then solder on small rings on the under side te form flanges or beads. These rings have tobc east separately, and turned oli smooth inside and out in a lathe, and then they are soldered on -to the plate aiioind the hole, and the inside or edge ofthe hole is then finished by scraping and burnishing. But the operation lof finishing the holes is necessarily imperfect, as the solder used is softer than the plate, and gives much trouble in the process of burnishing after the silver-plating. A sample of the work done by the common method is herewith submitted. I avoid this roundabout and expensive method of forming` 'the bead around'the hole, and all the objections to it, by a very simple mechanical process. I not only do that, but I make a far superior'job of it in every respect.

By my method I first punch the hole a, fig. 3. With another punch, formed for the purpose, I turn down the edge of the hole, as seen at b, same figure. Then with another tool or punch, which has a grooved shoulder, I turn down the edge of the hole b into the form of the bead vat c, thus forming the eruct-holes through the plate in a very rapid and perfect manner, thereby greatly improvinfar the appearance and chcapeninp,r -the article. A cross-section of the bead is seen at d, lig. 2, and an outside view is given at e, same `figure. j' is a tube on the under sideloi' the centre-plate A, through which thepivot-stand passes.

What I claim as new, andldesire to secure by Letters Patent, is

Forming the centre-plate A and thehcad around the cruet-holes of one and the same piece of metal, substantially as shown and described. i i
